This update for GraphicsMagick fixes several issues.

These security issues were fixed:

• CVE-2017-9262: The ReadJNGImage function in coders/png.c allowed attackers to cause a denial of service (memory leak) via a crafted file (bsc#1043353)
• CVE-2017-9261: The ReadMNGImage function in coders/png.c allowed attackers to cause a denial of service (memory leak) via a crafted file (bsc#1043354)
• CVE-2017-11750: The ReadOneJNGImage function in coders/png.c allowed remote attackers to cause a denial of service (NULL pointer dereference) via a crafted file (bsc#1051442)
• CVE-2017-12676: Prevent memory leak in the function ReadOneJNGImage in coders/png.c, which allowed attackers to cause a denial of service (bsc#1052708)
• CVE-2017-12673: Prevent memory leak in the function ReadOneMNGImage in coders/png.c, which allowed attackers to cause a denial of service (bsc#1052717)
• CVE-2017-12641: Prevent a memory leak vulnerability in ReadOneJNGImage in coders\png.c (bsc#1052777)
• CVE-2017-12935: The ReadMNGImage function in coders/png.c mishandled large MNG images, leading to an invalid memory read in the SetImageColorCallBack function in magick/image.c (bsc#1054600)
• CVE-2017-13147: Prevent allocation failure in the function ReadMNGImage in coders/png.c when a small MNG file has a MEND chunk with a large length value (bsc#1055374)
• CVE-2017-13142: Added additional checks for short files to prevent a crafted PNG file from triggering a crash (bsc#1055455)
• CVE-2017-14103: The ReadJNGImage and ReadOneJNGImage functions in coders/png.c did not properly manage image pointers after certain error conditions, which allowed remote attackers to conduct use-after-free attacks via a crafted file, related to a ReadMNGImage out-of-order CloseBlob call (bsc#1057000)
• CVE-2017-15218: Prevent memory leak in ReadOneJNGImage in coders/png.c (bsc#1062752)
